功能上的升级class MemoryManager: def init(self, allocator): self.allocator = allocator def allocate(self, process, request_size): memory_view = self.allocator.memory_view() block_start = None for i in range(len(memory_view)): if memory_view[i] is None: if block_start is None: block_start = i if i - block_start + 1 == request_size: self.allocator.allocate_memory(block_start, request_size, process) else: block_start = None return None

好的，下面是我为 `MemoryManager` 类添加的功能升级：

class MemoryManager:
    def __init__(self, allocator):
        self.allocator = allocator

    def allocate(self, process, request_size):
        memory_view = self.allocator.memory_view()
        block_start = None
        for i in range(len(memory_view)):
            if memory_view[i] is None:
                if block_start is None:
                    block_start = i
                if i - block_start + 1 == request_size:
                    self.allocator.allocate_memory(block_start, request_size, process)
                    return block_start  # 新增返回分配内存的起始位置
                else:
                    block_start = None
        return None

在原有代码的基础上，我新增了一个返回值，即分配内存的起始位置（block_start），并在找到合适的内存块后返回它。这样可以方便后续的内存使用，例如释放内存时就可以知道从哪个位置开始释放。
